Improvement in vises



ANSON P. STEPHENS, OF BROOKLYN, NEV YORK.

IMPROVEMENT IN VISES.

Speciiication forming part of Letters Patent No. 42,236, dated April 5, 1864.

To all whom, t may concern:

Be it known that I, ANsoN P. STEPHENS, of Brooklyn, inV the county of Kings and State otNew York, have invented a new and Improved Vise; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part ot' this specification, in which- Figure l is a side view of my invention; Fig. 2, a horizontal section of the same taken in the line :c w, Fig. l; Fig. 3, avertical section of the same taken in the line y y, Fig. 2; Figs. 4, 5, and 6, detached views of parts pertaining to the same. Fig. 7 is a horizontal section `in the line z z, Fig. 3.

Similar letters of reference indicate corresponding parts in the several ligures.

This invention relates to an improved vise ot' that class which are placed on benches or supports, and are commonly termed benchvises.77

The object ofthe invention is to obtain, by a simple arrangement or mechanism, vise of tie class specilied which will admit of its sliding or adjustable jaw being quickly adjusted to the work or article designed to be held by it and at the same time admit ot' the work or article bein g iml y grasped and held in the vise.

To enable those skilled in the art to fully understand and construct my invention, I will proce 3d to describe it.

A represents what may betermed the stock ofthe vise, the same being a box having one open side, in which a lever,B, works horizontally on an upright pin, u. This stock A has the permanent or iixed jaw B of the vise on its upper part at one end, and the ends ot' the stock have openings b b in them to admit of a bar, C, passing through the stock. This bar O may be of rectangular form,and it should be perfectly straight, so as to admit of it sliding freely in the stock A.

D is ajaw at one end ofthe bar G, the face of which is parallel with the face of thejaw B. The shank ot the jaw D has a horizontal projection, b, at each side of it, and these projections serve as a handle to move the bar O and the jaw D toward and from the xedjaw B. The bar C is provided with teeth e at its inner side, as shown in Figs. l, 2, 3, and 7. The lever B at its end, through which the pin c passes, has a projection, E, and also a hook projection, F, both of which are shown clearly in Figs. 2 and 7. Wit-hin the stock A there is a toggle, Gr, one part, d, of which is formed with a semicylindrical socket, e, to receive the cylindrical end f ot' the other part, d. (See Fig. 2.) This socket e is provided with a hook projection, g, at its lower end, and one may be used at its upper end, it' necessary or desired. The part d of the toggle is provided with a projection, h, one at its upper and the other at its lower edge, it' two hook projections, g, are employed. These projections h serve as stops for the hook projections g and prevent the two parts d d of the toggle being moved outward or backward beyond a certain dist nice. The end f of the part d of the toggle opposite tothe end )falso hasa semi-cylindrical form,and is fitted in a socket, z', at one end of a bar, H, which is provided with teeth j to engage with the teeth c of the bar C. The

bar H at the end opposite to that where the socket is formed is provided with an upright spur or arm, j against which asprin g, I, bears, said spring having a tendency to draw the bar H in the direction indicated by the arrow l in Fig. 2, and to keep said bar, as well as the toggle G, toward the bar C. The two parts, d d', of the toggle and the bar H are shown detached in Figs. 4, 5, and 6. By shoving the lever B toward the bar C the hook F ot' said lever will catch behind the socket c ot the part d of the toggle G, as shown in Fig. 2, and when the lever is thus shoved inward toward the bnr O. as indicated by arrow 2, the toggle will be drawn outward, so as to insure the bar H being free from the bar C and admit of the latter moving freely through the stock A, so that thejaw D may be moved directlyin contact with the article to be. grasped by the two jaws B D, and when the jaw D is thus adjusted the hook F, by drawing the lever B still farther outward in the direction indicated by arrow 2, will slipoit' from socket e, and the cam E ot said lever will act against the outer side of e and press the toggle G toward bar O, as indicated by arrow 3, and the bar H, by this movement ot' the toggle, engages with the bar C and moves it in the direction indicated by arrow 4, and causes the jaw D to press iirmly against the work, which will consequently be held between the two jaws B' D. Thus by this simple means the article or work to be grasped and held between the two jaws B D may be quickly adjusted in the vise and also quickly removed 123m it.

The vise may be cheaply constructed, and there are no parts liable to get out otl repair er become deranged by use.

Having thus described niy invention, what 'l claim as new, and desire to secure by Letters Patent, is

1. The toothed bar C, with jaw D attached, in Connection with the toggles G, toothed bar H, and the lever B and cain E, or their equivalents, for operating the toggle, all arranged substantially as and for the purpose herein set forth.

2. The hook F on the lever B, when used in connection with the toggle G and toothed bars C H, for the purpose specified.

3. The hook projections g g on the part d of the toggle, in connection with the projections h on the part d thereof, for the purpose set forth.
